I was cleaning my P-3AT and inadvertenly knocked out my hammer-spring pin. Well, I'm on my 2 nd day to try and get it re-installed in the grip to no avail. I know the hammer has to have the round end facing forward on the right side of the grip but getting the spring inserted has me stummped. There has to be a trick to this thing that makes it very easy but I haven't figured it out yet. Can anybody bail me out, or do I have to buy a new grip with hammer installed?
